I spoke to writer Kate Gartside and Executive Producer Mark Hedgecoe about BBC Two’s feature-length drama starring William Hurt, which tells the story of Richard Feynman’s involvement in the commission set up to discover the cause of the Space Shuttle Challenger disaster in 1986.

Feynman has long fascinated me but I knew little of his involvement with Challenger. Kate and Mark shared this fascination and talk brilliantly on how they took the facts of this final episode of his life and distilled it into a captivating drama.
